Title: Sampler for measuring diffused reflected light
Inventor: TAKAGI NOBUAKI
IPC: G01N21/35
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive sampler capable of detecting a large amount of diffused reflected light. SOLUTION: Metal is deposited on the surface of a ceramic substrate 11 with irregular micro recessions and protrusions to form a file surface of a thin membrane layer 14. When a solid sample is rubbed against the file surface, the sample is crushed at protruded parts 12, and a crushed sample 15 is held at recessed parts 13. When the file surface to which the sample is adhered is irradiated with measuring light, light transmitted inside the crushed sample 15 hits and is reflected at the surface of the thin membrane layer 14, transmitted inside the powder sample 15 and becomes emergent to the outside. As the light is not absorbed at the surface of the thin membrane layer 14, the intensity of diffused reflected light is increased. As this sampler is suited for mass production, the sampler becomes inexpensive.
